PNEUMATIC STACKER.

SPECIFICATION forming part of Letters Patent No. 599,279, dated February15, 1898. Application fil d March 22,1896. Serial No. 542,748. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE W. WOOD, residing at Woodburn, county ofMacoupin, State of Illinois, have invented a new and useful Improvementin Pneumatic Straw-Stackers, of which the following is a full and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to a new means of supporting and extending atelescope-extension stacker. Its object is to provide a device that willdo its work accurately, that will be easy to operate, and that is simplein construction. I accomplish this object by means of the mechanismillustrated in the accompanying drawings, in which-- Figure I representsa side elevation of the stacker extended to nearly its full length. Fig.II represents atop view of the same. Fig. IIIrepresents a cross-sectionthrough the line III III of Fig. I. Fig. IV represents a crosssectionthrough the line IV IV of Fig. I. Fig. V represents a cross-sectionthrough the line V V of Fig. I. Fig. VI represents a detail View of theratchet-wheel and click used to impart motion to the extension-section.

1 is the section of the stacker attached to the straw-exit of thethreshing-machine, but adapted to revolve thereabout.

2 is the extension-sleeve section, adapted to fit over the section 1.-

3 is a hood at the end of part 2 to direct the straw onto the stack.

4 is the turn-table, which is attached to the threshing-machine.

5 are side braces secured to other braces 6, said parts both beingsecured to the turn-table.

7 are side traveler-bars attached to braces 5 and having secured totheir outer end a ring 8. This ring 8 encircles but is not attached tothe extension 2.

9 is a pulley carried on the top of ring 8.

10 is a Windlass operated by the crank 11 and bearing a ratchet-wheeland a click at tachment.

12 is a draw rope or belt passing around the Windlass 10 and whose endsare fastened to a ring 13. The said ring 13 is secured to the lower endof the extension-sleeve 2.

14: are roller-wheels attached to the ring 13, one pair on each side andbearing one above and one below on the traveler-bars 7.

15 are also traveler-bars attached to the extension-sleeve 2, theirforward end secured to the rings 16, clamped about said sleeve 2, andtheir rear ends secured, as shown in Fig. V, to the ring 13. Y

17 are roller-wheels attached to the ring 8 and adapted to bear on thelower part of the traveler-bar 15.

18 is a rope operated by Windlass 19, adapted to raise or lower thestacker 011 the sleeve joint 22.

20 is a brace-bar to support the ring 8. 21 is a guy-rope, also tosupport said ring 8.

The device is operated as follows: The

straw is introduced into the cylinder of the stacker by the ordinarymeans. It is deposited through the outlet 3 at any point desired. Thisis accomplished by means of the mechanism I employ to extend the sleeve2. The crank 11 and Windlass 1O serve to wind and unwind the rope 12,and with it the ring 13, attached to the sleeve 2, is carried up or downthe cylinder 1. The weight of the lower portion of said sleeve 2 bearsagainst the trav eler-bar 7, and the friction thereof is reduced to aminimum by use of the roller-wheels 14.. They being situated both aboveand below said bar 7 allow neither upward nor downward motion. Thebalance of the weight is carried by the traveler 15, bearing against theroller-wheels 17. The angle of the cylinder may be increased ordiminished by lengthening or shortening the rope 18 by means of theWindlass 19. This construction affords a simple and compact means ofoperating the extension. It reduces the number of parts to a minimumwith a consequent diminution of weight and complexity. It affords ameans of easily directing the straw to any desired place and can beoperated easily and quickly.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In an improved pneumatic straw-stacker, the combination consisting of aframe secured to the machine and carrying a ring, a track secured tosaid frame and ring, an inner cylinder-section placed within said frameand outer cylinder-section on the inner cylindersection, substantiallyas described.
